Description

  The present invention relates to a gutter structure installed on a water-permeable pavement having a rainwater drainage function (general roads, highways, parking lots, parks, etc.), a gutter lid used for the gutter structure, and a method of constructing the gutter, Regarding water-permeable paved roads.

  As a gutter structure installed in a water-permeable pavement, a water passage hole is formed in the side wall of the side groove main body, rainwater is introduced into the water passage hole from the water-permeable surface layer of the pavement and flows into the side groove main body. What was made is known (refer patent document 1).

In this way, the side groove structure in which the water passage hole is formed in the side wall of the side groove body allows rainwater to flow from the water hole into the side groove body, so that the water passage hole needs to be enlarged in order to increase drainage efficiency. On the contrary, when the water passage hole is enlarged, there is a problem that the strength of the side groove body is lowered.
In addition, there has been a problem that the drainage capacity is reduced due to clogging of foreign matters such as dust and earth and sand in the water passage hole due to long-term use.
In particular, the side groove cover attached to the side groove body is exposed on the road surface, so there is also a problem that the side groove cover is damaged, and the side groove appears to be partitioned from the paved road, and the width of the roadway feels narrower accordingly. There was also a problem in terms of visibility.
Further, such a side groove structure is mainly intended to apply a side groove main body of a concrete secondary product in which a water passage hole is formed on a side wall in advance, and is unsuitable for concrete on-site construction.

  Conventionally, a water conduit is installed along the side groove body, rainwater that has passed through the water-permeable surface layer is collected by this water conduit, and flows into the inside of the side groove body from the water conduit through the water passage hole. Although there are some, there is a problem that the use of this water conduit is time-consuming to construct and disadvantageous in terms of cost.

As a side groove structure for a water-permeable pavement that can solve these problems, the side groove cover has a two-layer structure in which a water-permeable concrete layer is combined on a water-permeable concrete layer, A technique is known in which rainwater is introduced into a water-permeable concrete layer and flows into a gutter body from a through-hole formed in the non-water-permeable concrete layer (see Patent Document 2).
Japanese Patent Publication No. 2001-26974 Japanese Patent Publication No. 2000-179034

However, in the lateral groove structure of Patent Literature 2, it is necessary to form a water-permeable wall portion with water-permeable concrete at the upper end portion of the side wall of the side groove main body, and the water-permeable surface layer of the pavement road, the water-permeable wall portion, Since the water-permeable concrete layer of the side ditch cover is a separate structure and is not continuously integrated, the flow of rainwater gradually passes from the water-permeable surface layer of the pavement to the water-permeable concrete layer of the side ditch cover through the water-permeable wall. It will be everything.
In addition, since a streak is formed at the boundary between the water-permeable surface layer of the paved road, the water-permeable wall, and the water-permeable concrete layer of the side groove cover, it is easy for clogging of dirt, sand, etc. to this line, impeding the flow of rainwater Resulting in.
Thus, in the above-mentioned side groove structure, there is a problem that smooth fluidity of rainwater cannot be secured, leading to a decrease in drainage efficiency, and the water-permeable surface layer of the paved road and the water-permeable wall portion. In addition, since the water-permeable concrete layer of the side groove cover is a separate body, there is a problem that a step is easily generated at the boundary portion and the edge portion is easily damaged.
Moreover, since it is necessary to form a water flow wall at the upper end of the side wall, it takes time and labor to manufacture the side groove body, and the side groove cover also has two layers, a water-permeable concrete layer and a water-permeable concrete layer. Since it needs to be formed into a structure, there is a problem that it takes time and labor to manufacture.

Hereinafter, embodiments of the present invention will be described based on examples shown in the drawings.
FIG. 1 is a cross-sectional view showing an embodiment of a side groove structure for a water-permeable pavement according to the present invention, and FIG. 2 is a perspective view of a side groove cover used in the side groove structure.

  In this lateral groove structure, a lateral groove is installed on the shoulder portion of the water-permeable paved road 1 (water-permeable paved road). The water-permeable paved road 1 is a non-water-permeable base layer as a base layer on the ground 10. 11 is formed, and a water-permeable surface layer 12 (hereinafter referred to as “paved road-side water-permeable surface layer”) is formed on the non-water-permeable base layer 11.

The side groove structure includes a side groove main body 2 and a side groove lid 3 that is attached to the upper surface opening 20 of the side groove main body 2.
The side groove main body 2 is manufactured as a concrete secondary product, is surrounded by a bottom portion 21 and left and right side walls 22 and 23, is formed in a substantially U shape having an upper surface opening portion 20, and has an inner bowl shape. A lid receiving step 25, 25 is formed at the upper end of the inner surface of each of the side walls 22, 23.
Further, the pavement side wall 23 of the gutter body 2 is formed such that the upper end surface 26 thereof is positioned substantially the same as the boundary 13 between the non-water-permeable base layer 11 and the pavement side water-permeable surface layer 12.
Although not shown in the drawings, the gutter body 2 is installed on a base made of a basic crushed stone layer, a basic concrete layer, and a mortar layer.

The side groove lid 3 is mounted on the upper surface opening 20 of the side groove main body 2 so as to be placed on the lid receiving steps 25, 25.
As shown in FIG. 2, the side groove cover 3 is formed in a parallel state in which several (six in the embodiment) angle-shaped members 30 (angle-shaped steel) having corners at the tops are held with a gap S serving as a water inlet 31. In addition, the connecting members 32 are connected by two (or more) connecting rods 32 as connecting members.
In this case, the angle of the connecting rod 32 is reduced, for example, and the angle molds 30 are flexibly connected so that twisting and bending occur at the connection part. However, the side groove cover 3 can be mounted without backlash.
It should be noted that the gap S between the adjacent chevron molds 30 and 30 is set in consideration of both of them because the groove side water-permeable surface layer 4 described later falls when it is too wide, and the water permeability of rainwater decreases when it is too narrow. However, in the embodiment, it is set to around 5 mm.
The top surface of the chevron mold 30 is plated with zinc or the like.

Then, in a state where the side groove cover 3 is mounted on the upper surface opening 20 of the side groove main body 2, it is integrated with the pavement side water-permeable surface layer 12 from the upper end surface 26 of the pavement side wall 23 to the entire upper surface of the side groove cover 3. A side groove structure for a water-permeable pavement is formed by covering with a continuous side groove side water-permeable surface layer 4.
In this case, the construction of the pavement side water-permeable surface layer 12 is performed simultaneously with the construction of the side groove side water-permeable surface layer 4.

Accordingly, rainwater on the water-permeable pavement 1 permeates the pavement-side water-permeable surface layer 12 and is prevented from penetrating into the basement by the non-water-permeable underlayer 11. It flows in the side groove side water-permeable surface layer 4 and then flows into the drainage channel 24 of the side groove body 2 from the water inlet 31 (gap S) of the side groove lid 3 and is drained.
Moreover, the rainwater on the side groove side water-permeable surface layer 4 permeates the side groove side water-permeable surface layer, and directly flows into the drainage channel 24 of the side groove body 2 from the water inlet 31 (gap S) of the side groove lid 3 and is drained. The

In this embodiment, the base layer is formed on the non-water-permeable base layer 11, but the base layer may be formed on the water-permeable base layer.
In this case, most of the rainwater that has permeated the pavement side water-permeable surface layer 12 permeates the water-permeable foundation layer and permeates into the ground 10. It flows in the direction of the road shoulder, continues to flow in the side groove side water-permeable surface layer 4, flows into the drainage channel 24 of the side groove body 2 from the water inlet 31 (gap S) of the side groove lid 3, and is drained.

And since the ditch side water-permeable surface layer 4 is integrally formed continuously with the pavement side water-permeable surface layer 12, a boundary is formed between the pavement side water-permeable surface layer 12 and the side groove-side water-permeable surface layer 4. There is no.
As a result, rainwater flows continuously from the pavement-side water-permeable surface layer 12 to the side-groove-side water-permeable surface layer 4 in a stepwise manner instead of stepwise, and between the pavement-side water-permeable surface layer 12 and the side-groove-side water-permeable surface layer 4 Therefore, there is no clogging of dirt, earth and sand, etc., rainwater can flow smoothly, and as a result, drainage capacity can be improved.

  Moreover, since the pavement side water-permeable surface layer 12 can be performed simultaneously with the construction of the side groove side water-permeable surface layer 4, it is not necessary to set the construction of the pavement side water-permeable surface layer 12 as a separate process, and the construction period is greatly shortened. In addition, the quality of the pavement side water-permeable surface layer 12 and the side groove-side water-permeable surface layer 4 can be made uniform.

Further, since the side groove cover 3 is entirely covered with the side groove side water-permeable surface layer 4, the side groove cover 3 is not exposed to the road surface.
Therefore, there is no problem that the side groove cover 3 is broken, and the width of the pavement is increased by the width of the side groove, so that the visibility is improved and a margin can be given to driving.

Further, since the side groove cover 3 has a structure in which several angle-shaped members 30 (angle-shaped steel) are connected in a parallel state holding the gap S, the side groove cover 3 can be easily manufactured. 31 is opened in a slit shape, and water can be collected at the water inlet 31 by the slope formed by the mountain-shaped mold material 30, so that even a large amount of rainwater can be reliably passed.
In addition, since the chevron molds 30 are arranged side by side, the upper surface thereof is formed in a chevron-shaped uneven surface, and is in a state of biting into the side groove side water-permeable surface layer 4. This prevents slippage between the side groove side water-permeable surface layer 4 and the side groove lid 3, and prevents deformation and distortion due to the side groove side water-permeable surface layer 4 moving.
In addition, when the chevron mold member 30 is used, it is placed in a point contact state with respect to the lid receiving steps 25, 25, so that the mounting state of the side groove lid 3 can be stabilized.
Further, when the top surface of the chevron mold 30 is plated with zinc or the like, the side groove attached to the chevron mold 30 can be obtained by reversing the side groove cover 3 and applying an impact when the side groove cover 3 is removed. The side water-permeable surface layer 4 can be easily peeled off, and the reuse treatment of the side groove lid 3 can be simplified.

In this embodiment, the side groove main body 2 is a secondary concrete product, but the side groove main body 2 may be formed by concrete on-site construction.
As for the side groove cover 3, for example, as shown in FIGS. 3 and 4, several angle-shaped members 30 (angle-shaped steel) with the corners at the tops are used as the water inlet 31. A side groove lid having a structure in which the gaps S are held in parallel and connected by a connecting member 35, or several (six in the illustrated example) square members 33 as shown in FIG. A side groove cover having a structure in which two (or two or more) connecting rods 32 as connecting members are connected to each other in a parallel state, and the upper surface is formed as an angled uneven surface 34 as shown in FIG. In addition, a concrete side groove cover having a water passage 31 opened in the valley portion, a normal water-dropped concrete side groove cover having a flat upper surface, or the like can be used.

Next, FIG. 7 is process explanatory drawing which shows one Example of the construction method of the side groove structure for water-permeable pavement of this invention.
In this construction method, when the non-water-permeable pavement 5 is renovated to the water-permeable pavement 1, a case where a gutter is simultaneously refurbished is taken as an example.

As shown in FIG. 7A, the non-water-permeable pavement 5 is formed with a non-water-permeable base layer 11 and a non-water-permeable asphalt layer 51 on the ground 10. A side groove 6 having a normal structure is installed in the part.
And in order to renovate this water-impermeable pavement 5 to the water-permeable pavement 1, the asphalt layer 51 is stripped off as shown in FIG. In some cases, both the water-impermeable base layer 11 and the asphalt layer 51 are peeled off.
Further, the side groove cover 7 of the existing side groove 6 is removed, and the upper end portion of the pavement side wall 23 in the side groove main body 2 is cut away as shown by a broken line in FIG. In this case, the excision is performed so that the upper surface thereof is substantially the same as the upper surface (boundary 13) of the non-water-permeable base layer 11 or located below the upper surface (boundary 13) of the non-water-permeable base layer 11.

Next, as shown in FIG. 7C, the side groove lid 3 is attached to the upper surface opening 20 of the side groove main body 2 in a state of being placed on the lid receiving steps 25 and 25.
Next, a pavement-side water-permeable surface layer 12 is formed on the non-water-permeable base layer 11, and the pavement-side water-permeable surface layer 12 is continuously integrated with the pavement-side water-permeable surface layer 12, so that the entire upper surface of the side groove lid 3 extends from the upper end surface 26. The side groove side water-permeable surface layer 4 is formed so as to cover it. In this case, the pavement-side water-permeable surface layer 12 is formed simultaneously with the construction of the side-groove-side water-permeable surface layer 4, thereby renovating the non-water-permeable pavement 5 to the water-permeable pavement 1 and completing the modification of the side grooves. .
When the non-water-permeable pavement 5 is repaired, when both the non-water-permeable base layer 11 and the asphalt layer 51 are peeled off, the pavement-side side wall 23 of the side groove body 2 has the same height as the upper end surface 26. A non-water-permeable base layer 11 (which may be formed as a water-permeable base layer) is formed, and a pavement-side water-permeable surface layer 12 and a side-groove-side water-permeable surface layer 4 are formed thereon so as to be integrated continuously by simultaneous construction. It will be.

In this construction method, the existing side groove main body 2 is used. For the side groove main body 2, it is only necessary to add a simple labor to cut off the upper end portion of the pavement side wall 23. Just replace it.
In addition, since only the upper end of the pavement side wall 23 is cut away, it is not necessary to cut the other side wall 22 on the private side. Can be avoided.

  Moreover, in order to continuously form the side groove side water permeable surface layer 4 continuously with the pavement side water permeable surface layer 12, the side groove side water permeable surface layer 4 can be constructed simultaneously with the construction of the pavement side water permeable surface layer 12, The quality of the pavement side water-permeable surface layer 12 and the side groove side water-permeable surface layer 4 can be made uniform, and the construction period required to form this side groove-side water-permeable surface layer 4 can be greatly shortened.

  In the present invention, the side groove main body 2 is a bottomed side groove main body, but may be a bottomless side groove main body having an open bottom.

Next, FIG. 8 is a sectional view showing another embodiment of the side groove structure for a water-permeable pavement of the present invention.
In this gutter structure, a gutter is installed so as to cross the water-permeable paved road 1 (water-permeable paved road). A ground layer 11 is formed, and a water-permeable surface layer 12 (hereinafter referred to as a “paved road-side water-permeable surface layer”) is formed on the non-water-permeable base layer 11.

  In this embodiment, since the side grooves are provided so as to cross the water-permeable pavement 1, the left and right side walls 22, 23 of the side groove main body 2 are pavement side walls, respectively. The upper end portions 26 and 26 of the upper end portions of the side walls 22 and 23 have a boundary 14 between the water-impermeable base layer 11 and the ground 10 (from a boundary 13 between the water-impermeable base layer 11 and the pavement side water-permeable surface layer 12). It is excised so as to be positioned substantially the same as (lower).

In the state where the side groove cover 3 is mounted on the upper surface opening 20 of the side groove main body 2, the entire upper surface of the side groove cover 3 is covered with the side groove side water-permeable surface layer 4 continuously integrated with the pavement-side water-permeable surface layer 12. In this case, the non-water-permeable base layers 11 and 11 are formed so as to extend over the upper end surfaces 26 and 26 of the paved road side walls 22 and 23.
The other configuration is the same as that of the embodiment shown in FIG.

  Moreover, in an Example, as shown in FIG.1 and FIG.7, the example which installed the side groove in the road shoulder part of the water-permeable pavement 1 (water-permeable pavement road), and as shown in FIG. We gave an example of installing a gutter to cross a water-permeable paved road), but installing a gutter around a parking lot or park, or installing a gutter to cross a parking lot or park, etc. Of course, the configuration of the present invention can also be applied to cases.
